Table 4: Properties of the 25 confirmed companion stars found around the 22 members in our NACO survey and the 9 members with multi-color observations in the ADONIS survey. The columns show the secondary designation, the J, H, and $K_{\rm S}$ magnitudes, the angular separation, and the position angle (measured from North to East). Magnitude lower limits are given if a secondary is not detected in a filter. We list the absolute magnitude and corresponding mass in columns 7-10. The 11th column lists the status of the object (c = confirmed companion star, nc = new confirmed companion star). The last column shows additional remarks. A "J'', "H'', or "K'' means that the secondary flux in this filter was obtained from the image obtained without the NDF, using the PSF from the corresponding image that was obtained with NDF (see Sect. 2.4). Properties of the observed primaries, candidate companions, and background stars are not shown here; these are listed in Table A.1.
